Energy efficiency in New Zealand's residential sector: A systemic analysis

This paper examines the complexity arising from the multiple, time varying factors that impact energy efficiency in New Zealand's residential sector. Initial problem structuring involved the analysis of behaviour over time of main variables and incorporated stakeholder analysis using a systems approach. Further, a systems model of the problem situation was developed using a participative group model building process. The analysis of the model revealed a set of feedback loops operating in the system identified as responsible for the complexity of the problem situation relating to energy efficiency. The paper concludes by highlighting some of the main results relating to long-term structural changes suggested by the stakeholders involved in this study to change the behaviour of the system.
